fix: remove rlement endpoints and links from the HealthChat

* fix(healthchat): switch off analytics, crash and bug reporting endpoints

Upstream ships *.localhost placeholders in Secrets.swift and marks the file assume-unchanged; with analytics on, the Element Call widget was handed Element's own PostHog and Sentry. nil hides the analytics prompt, the Analytics and Report a problem entries until HealthChat runs its own services.

* feat(healthchat): hide the Labs entry in settings

* fix(healthchat): point Copyright and the analytics terms at healthchat.ch

* docs(healthchat): add the 26.11.1 release notes

* feat(healthchat): drop the Element help links

* feat(healthchat): switch off location sharing

* test(healthchat): skip the analytics suite without PostHog
